I'm the author of the driver included in the kernel from 3.1: http://git.kernel.org/?p=linux/kernel/git/tiwai/sound.git;a=commitdiff;h=0f… an example of the modprobe conf files: http://files.parisson.com/debian/fast-track-pro.conf As Paul said, this device is indeed class compliant so it can works in stereo 16 bits mode on any kernel version.. But, to get its special features (24 bits mode, spdif, etc..), we need some quirks provided by my patch. But, I know the current driver is not perfect, mainly because we can't get the 4 output channels working.. So you are welcome to participate and improve it! I can just strongly advise you to start from the current state of the driver so that the maintainer of the alsa part (Takashi Iwai) can merge it properly.. Cheers, G
